In heating mode, the maximum leaving water flow temperature
(T1stoph) that heat pump can reach in different outdoor
temperature (T4) is listed below:
In DHW mode, the maximum domestic hot water tempera-
ture(T5stop) that heat pump can reach in different outdoor
temperature(T4) is listed below:
The unit have a freeze prevention function that uses the heat
pump to keep the water system safe from freezing in all
conditions. Since a power failure may happen when the unit is
unattended, It's suggested to use anti-freezing flow switch in
the water system. (Refer to 9.4 Water piping).
In cooling mode, the minimum leaving water flow tempera-
ture(T1stoph) that the unit can reach in different outdoor
temperature(T4) is listed below:

HEATING MODE
If you add the backup heater in the system, the backup heater
can increase the heating capacity during cold outdoor
temperatures. The backup heater also serves as a backup in
case of malfunctioning and for freeze protection of the outside
water piping during winter time. The capacity of backup heater
for different units is listed below.

If IBH/AHS setting is valid, only IBH/AHS turns on;
If IBH/AHS setting is invalid, only heat pump turns on;
*If the system is installed in parallel,Tbt1 must be connected and installed in the balance tank.
**If the volume of the balance tank is relatively large, in order to ensure the use effect, it is recommended to add a Tbt2 sensor
in the lower part of the balance tank.
**When the units are connected in parallel, such as when the communication between the unit is unstable (such as an
Hd fault code),
add a network matching wire between the ports H1 and H2 at the terminal of the communication system;
Sensors Tbt1, Tbt2, T5 and extension wire can be shared, sensors Tw2, Tsolar and extension wire can be shared, if these functions
are needed at the same time, please customize these sesors ande extension additionally.
3 ACCESSORIES

To avoid injury, do not touch the air inlet or aluminum fins of the unit.
Do not use the grips in the fan grills to avoid damage.
The unit is top heavy! Prevent the unit from falling due to improper inclination during handling.
CAUTION
Before installation:
Be sure to confirm the model name and the serial number of the unit.
Handling:
Due to relatively large dimensions and heavy weight, the unit should only be handled using lifting tools with
slings. The slings can be fitted into foreseen sleeves at the base frame that are made specifically for this purpose.
